I bought this new laptop and now whn I type faster or put my fingers relaxed and then type quickly.. every 2 or 3 letters I try to type the cursor or jumps back 4 or 5 letters or deletes the whole world and then starts from there or the cursor ends up in another tab or table etc or the window suddenly gets minimized(it is not a virus.. it is the damn keyboard). I tried tried typing slowly to see if my fingers hit some other button by mistake but I don't see it .. even if it did.. what kinda button on the whole keyboard makes the cursor jump few lines back or few letters back or delete half of a word and start there. I really had to stop and type this extremely slowly like if I was typing on a blackberry or something.. it is f---ing annoying as hell.. do I have to return this piece of crap now??? btw if you are interested it is a ACER ASPIRE AS5315-2848 LAPTOP PC(2.1GHz/1GB).

The only thing that comes to mind is that you are accidently hitting the mouse touchpad as you type... this would explain the problem. Try turning off the touchpad and test to eliminate it as the cause.

yes :) .. did a google search and the ultra sensitive touchepad seems to driving alot of Acer users crazy. for now i have found out to hit Fn + F7 to disabled the touchepad but that is temporary.. ALL ACER users seem to not find the touchepad settings anywhere so I am currently searching for that to permanently turn this crap thing off.

You can uninstall the touchpad thru Device Manager.
